Description
Schauvorrichtung'mit Absorptionsglas für starke Lichtquellen. Die Erfindung betrifft eine Schauvorriih= tung, die es ermöglicht, ohne Reizung des Auges starke Lichtquellen, wie die Sönne, glühende Massen, Bogenlicht usw., zu beobachten.Display device with absorption glass for strong light sources. the Invention relates to a Schauvorriih = device that allows without irritation of the Eye's strong light sources, such as the sun, glowing masses, arc light, etc., to observe.
In der Hauptsache besteht,die Vorrichtung aus einer Röhre, deren schräg geschnittenes Ende mit einem Absorptionsglase verschlossen ist, und vor dem eine zweite Glasscheibe schwenkbar so angeordnet ist, daß die Strählen der Lichtquelle an der dem Rohre zugewandten Fläche .,der Glasscheibe zurückgeworfen und durch das Absorptionsglas hindurch in die Röhre gelenkt wird.In the main, the device consists of a tube, whose inclined cut end is closed with an absorption glass, and in front of the one second pane of glass is pivotably arranged so that the rays of the light source on the surface facing the tube., thrown back the glass pane and through the Absorption glass is directed through into the tube.
Die Zeichnung stellt ein Ausführungsbeispiel des Erfindungsgegenstandes dar. Das Rohr i ist schräg geschnitten mit dem Absorptionsglase 2 abgedeckt, vor, dem .die Reflexscheibe 3 schwenkbar und .durch die Bogenschiene 4 feststellbar angeordnet ist.The drawing represents an exemplary embodiment of the subject matter of the invention. The tube i is cut at an angle and covered with the absorption glass 2, in front of which the reflective disk 3 is arranged to be pivotable and lockable by the curved rail 4.
D'ie Strahlen der Lichtquelle 5 fallen auf die Scheibe 3, werden von hier auf die Absorptionsscheibe 2 zurückgeworfen und durch das Rohr i hindurch auf deren Innenseite dem Auge sichtbar.The rays of the light source 5 fall on the disk 3, are of here thrown back onto the absorption disk 2 and through the tube i the inside of which is visible to the eye.
